A circuit board comprising:
- a base substrate having a device mount area defined thereon;
- a first wiring pattern formed on a first surface of the base substrate;
- a dummy pattern formed on the base substrate, wherein at least a part of the device mount area is filled with the dummy pattern;
- a first protective layer covering the first wiring pattern and the dummy pattern;
- and
- a lead pattern formed on the first protective layer, wherein the lead pattern is extended to the device mount area.
A method of fabricating a circuit board, the method comprising:
- providing a base substrate having a device mount area defined thereon;
- forming a wiring pattern and a dummy pattern on a first surface of the base substrate, wherein the dummy pattern is formed in the device mount area;
- forming a first protective layer to cover the wiring pattern and the dummy pattern;
- and
- forming a lead pattern extended from the device mount area on the first protective layer.
